CHURN.

STPECIFICATION forming part of Letters Patent No. 554,784, dated February 18, 1896. Y

Application led July Z9, 1895. Serial No. 557,463. (No model.)

To all whom, t may concern:

Be it known that l, WILLIAM D. LINTON, a citizen of the United States, residing at Vernon7 in the county of Marion and State of Illinois, have invented a new and useful Churn, of which the following is a speciiication.

This invention relates to certain new and useful improvements in churns of that class in which the churn-body receives a vibrating or shaking movement; and the object of the improvement is the provision of simple and efficient means for securing the churn-body upon a vibrating platform and in the employment of an easily-operated mechanism for vibrating or oscillatin g the said platform, whereby the churning process is rendered comparatively easy and facilitated.

Other objects and advantages are contemplated and will become manifest as the nature of the invention is understood; and the improvement consists of the novel features and combinations of the parts which hereinafter will be more fully set forth and claimed, and which are shown in the accompanying drawings, in which- Figure l is a side elevation of a churn constructed in accordance with the present invention, the upper portion of the churn-body being broken away so as to disclose more clearly the relative arrangement of the churncover and the cap. Fig. 2 is a top plan view thereof.

The framework comprises longitudinal sills -1, upper side beams 2', cross-bars 3, and uprights 4. The vibrating platform 5 is reduced at one end, and is pivotally connected at the reduced end with the lower extremity of the pitman 6, by means of which motion is transmitted from the actuating mechanism to the said platform. A shaft 7 is secured near its ends in brackets 8, pendent from the lower side of the platform and located in proximate relation to the edges and about midway of the ends thereof. The end portions of the shaft 7 extend beyond the sides or edges of the platform and provide journals which obtain bearings in blocks-or castings 9 secured upon the longitudinal sills 1. A standard 10 is rmly attached at its lower end to the platform 5, and its upper end curves so as to overhang the churn-body 11 and terminates in a horizontal extension 12, which is vertically apertured to receive a binding-screw 13 whose thread corresponds with the thread of the said aperture. A brace 14 is secured at its lower end to the platform 5 at a distance from the foot of the standard 10, and its upper portion has at-4 tachment with the upper end of the standard 10, as shown at 15, and with the curved end thereof, as shown at 16, thereby strengthening the said standard and the overhanging portion thereof and rendering the latter capable of withstanding the strain incident to clamping the churn-body 11 upon the platform 5.

The churn-body 11 may be of any pattern, and is supplied with side handles 17 and with a contracted neck to which is fitted a cover 18 in the usual manner. A cap 19 fits over the neck of the churn-body, and its flange 2O embraces the sides of the said neck, so as to prevent lateral displacement of the said cap when iitted upon the churn-body. A boss or enlargement 21 is centrally disposed upon the cap 19 and has a recess in its top side to receive the lower end of the binding-screw 13, thereby causing positive engagement between the said binding-screw and cap. Thus it will be seen that when the churn-body is properly positioned upon the platform 5 and the binding-screw 13 being turned to press the cap closely against the neck of the body the latter will be clamped between the said platform and the cap, the degree of pressure being regulated by a proper manipulation of the binding-screw 13, as will be readily comprehended.

A balance-wheel 22 is suitably mounted at one end of the framework and is provided with a handle 23 for the application thereto of manual power, and motion is transmitted from the balance-wheel 22 to the shaft 24 at the opposite end of the machine by means of a belt 25, which passes around the wheel 22, and a pulley 26 on the outer end of the said shaft 24. The opposite end of the shaft 24 is provided with a 1iy-wheel27 to give steadiness and uniformity to the movements of the vibrating platform. The crank 2S of the shaft 24 has the upper end of the pitman 6 connected therewith in the usual manner. By driving the balance-wheel 22 motion will be imparted to the shaft 24 and will be transmitted therefrom to the platform 5 by the instrumentali- IOO ties herein set forth, and the cream contained in the ehurn-body will be thoroughly agitated, so as to have its butter globules broken in the usual manner.

The invention may be provided in a variety of forms, according to the design of the manufacturer. Therefore it is to be understood that in the embodiment of the same changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Ilaving thus described the invention7 what is claimed as new isl. In a churn, the combination with a vibrating platform and actuating mechanism therefor, of a standard firmly attached to the said platform and having its upper end curved to extend over the platform and terminating in a horizontal extension, a bindingscrew operating in a threaded opening of the said horizontal extension, a brace secured to the platform a distance from the foot of the standard. and extending diagonally and crossing the standard and the curved end portion thereof and lirml y attached to each at the point of crossing, a churn-body mounted upon the platform, and a cap fitted to the upper end of the churn-body and adapted to receive the end-thrust of the binding-screw by means of which the said churn-body is clamped between the platform and the horizontal extension of the aforesaid standard, substantially in the manner set forth.

2. The herein .shown and described churn,

comprising a framework having side bearings, a vibrating platform contracted at one end and having laterally-extending journals midway of its ends mounted in the said bearings, a vertical standard secured to the platform at a middle point and having its upper end curved to extend over an end of the platform and terminating in a horizontal extension, a binding-screw operating in a threaded opening of the said horizontal extension, a brace attached at its lower end to the contracted end of the platform a distance from the foot of the standard and extending diagonally and crossing the upper portion of the standard and the curved extremity thereof and secured to each, a churn-body mounted upon the platform and having its upper end con tracted and closed by a cover, a cap fitted to the upper end of the churn-body and having a plate secured to its upper side, and which is recessed to receive the lower end of the said binding-screw, a shaft having a crank, a pitman connecting the crank with the contracted end of the vibrating platform, and means for rotating the said shaft for imparting motion to the said vibrating platform, substantially as set forth for the purpose described.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in the presence of two witnesses.
